OTS514 hydrochloride

OTS514 hydrochloride is a highly potent TOPK inhibitor, which inhibits TOPK kinase activity with a median inhibitory concentration (IC50) value of 2.6 nM. OTS514 hydrochloride strongly suppresses the growth of TOPK-positive cancer cells. OTS514 hydrochloride induces cell cycle arrest and apoptosis.

How to use

In Vitro:

OTS514 (1.5625-100 nM) induces cell cycle arrest and apoptosis at nanomolar concentrations in a series of human myeloma cell lines (HMCL) and prevents outgrowth of a putative CD138+ stem cell population from multiple myeloma (MM) patient-derived peripheral blood mononuclear cells.

In Vivo:

OTS514 (1-5 mg/kg; once a day for 2 weeks; intravenous administration) induces tumor regression in a xenograft model of A549 cells (TOPK-positive lung cancer cells).
